I recently upgraded to 14.04 with the nvidia-331 driver (Dell Latitude E6430). The performance is lightning fast with the exception of playing video like YouTube or Skype. According to indicator-sensors the NVMS 5200 temperature rises right up to 95+ C (Other temperatures stay below 80), and indicator-cpufreq immediately reduces cpufreq to the minimum to cool the machine down. Consequently if I set off a video by accident, I have to suspend Ubuntu and let it cool for a few minutes to avoid moving at a snail's pace.

I love the performance of the driver otherwise, and would love to just tweak a system setting so that the card just paces itself a bit when Skyping or playing Flash, rather than revert drivers. Is there such a setting? I shouldn't have to buy a cooling fan to Skype just because of a driver upgrade.
